In my experience mobile cpus run at about 75%-90% the single-core performance of desktop counterparts. Zen 3 APUs will be close. Isn't the M1 fabbed on TSMC 5nm? Zen 3 is on 7nm. If a Zen 3 APU will run close to Apple Silicon I will be mightily impressed.

So you mean Apple has this huge advantage of 5nm compared to 7nm but failed to outperform AMD? What a failure. (that was sarcasm. My take is this performance is impressive but you should not be surprised if it does not completely outperform CPUs that should be less efficient)

It is Apple Silicon that is faster (at least on paper). I'm saying I think even though AMD will have worse perf/watt, I think it will get impressively close despite it's less efficient fabrication process.

Best single core scores for Ryzen 2 on Passmark: * 3800X (105W desktop) scores 2855 * 4900H (45W mobile) scores 2707 or 95% of 3800X * 4750U (15W mobile) scores 2596 or 91% of 3800X

  They are not even of same series. 3700U(fastest Ryzen 3000 15W processor) single core is 57.5% of 3700X(not the fastest Ryzen 3000 desktop).

    AMD's naming scheme has mislead you. Renoir is 7nm Zen 2 aka the 4000 series. https://en.wikichip.org/wiki/amd/cores/renoir https://en.wikichip.org/wiki/amd/cores/renoir Matisse is also 7nm Zen 2 aka the desktop 3000 series. https://en.wikichip.org/wiki/Matisse https://en.wikichip.org/wiki/Matisse Picasso is 12nm Zen+ aka the mobile 3000 series. https://en.wikichip.org/wiki/amd/cores/picasso https://en.wikichip.org/wiki/amd/cores/picasso

  That's pretty good. For geekbench we see: * 3800XT = 1357 (100%) * 4800H = 1094 (~80%) * 4800U = 1033 (~76%) I would expect a 5800U to score at best around 1500, but realistically closer to 1300-1450. That's still behind the M1, but pretty darn close for being behind a node (and will still probably be faster for applications that would require x86 translation).
